Description
Technical field
The present invention relates to be used for the transverse link of wheel suspension and relate to the use of this transverse link in the independent wheel suspension, particularly rear wheel suspension of the non-wheel flutter of power actuated vehicle.
Background technology
Three important parameters of decision motor vehicle wheel position are camber angle and bundle angle.The present invention be specifically related to power actuated vehicle vertically on essence power (rearward-directed force) backward act on the control (internal beam control (toe-in control)) of bundle angle angle (toe angle) under the situation of wheel; This situation is common; For example be, during the power actuated vehicle speed-down action and particularly during brake.
In the speed-down action process; And therefore when rearward-directed force acts on wheel; This rearward-directed force points to the point of attachment that links to each other with this wheel stand of the transverse link of wheel side through the wheel stand that is connected to wheel, and the relative vehicle body of transverse link moves backward, and it is through the elastic bearing of body side; Particularly pivot bearing links to each other with vehicle body.In this motion process, elastic bearing, particularly elastic bearing lining, flexibly distortion.
Elastic deformation have concurrently bearing lining vertically on parts and the parts that make progress with respect to the footpath of bearing lining.Particularly; The bearing of the relative car body side of rearward-directed force that acts on the point of attachment of wheel side applies moment of torsion, therefore, and when on longitudinal direction of car, observing; The load radially outward of the bearing of front body side; Promptly from the outwards load on the direction of the point of attachment of wheel side of the bearing of front vehicle body side, and when power actuated vehicle is observed on vertically, the load on the bearing direction of aftercarriage side of the bearing of aftercarriage side.Bearing lining elastic deformation diametrically makes in rearward-directed force process transverse link and therefore coupled wheel except linear reverse, also produce in fact and rotatablely moves; And this rotatablely moves and causes the change at wheel bundle angle, and the change of above-mentioned bundle angle angle reduces internal beam (toe-in) or increases outer open (toe-out).
Such transverse link of just discussing is the theme of many publications.Therefore; For example; EP0 220 851 B1 patent documentations disclose a kind of transverse link, and its dependence is connected in the bundle angle correction coupler of the pivot bearing of body side and controls the bundle angle angle of the wheel of the point of connection that is linked to wheel side with respect to the power that acts on the wheel on the longitudinal direction of car.In each case, bundle angle correction coupler one end is connected in the pivot that transverse link itself and the other end are connected in the pivot bearing of body side.

Described transverse link, trigonometric sum has identical size for the 4th jiao.
Described transverse link, the elastic bearing lining, the rigidity that makes progress of specific diameter is low in fact for its rigidity on axially, axially with radial rigidity than preferably approximately 1: 10.
Described transverse link provides the pivot bearing of front vehicle wheel side and the pivot bearing of rear wheel side on the point of attachment of wheel side, wherein the pivot bearing of forward and backward wheel side is established the pivot axis of wheel side.
The application of described transverse link in the independent wheel suspension, particularly rear wheel suspension of the non-wheel flutter that is used for power actuated vehicle.
The characteristic that should be noted that above narration can combine and represent other structure of the present invention with suitable manner any needs, technical.Specification sheets is described and is offered some clarification on characteristic of the present invention, especially also combines with accompanying drawing.
The pivot axis bevelled idea of the body side of the transverse link that the present invention comes down to establish with respect to pivot bearing based on the back pivot bearing axis of the pivot bearing of the preceding pivot bearing axis of the pivot bearing that makes the front body side and/or back body side, promptly before pivot bearing axis and/or back pivot bearing axis with respect to the pivot axis of body side set or arrange make its not with the pivot axis in-line of body side.
The pivot axis of body side is established by the connection lead at the center of the pivot bearing that connects each body side in fact, and the center of pivot bearing is interpreted as middle part and the point on the pivot bearing axis of relevant pivot bearing that is positioned at pivot bearing with respect to width.
In a preferred structure, the low elastic bearing of rigidity that the ratio of rigidity on the pivot bearing of body side has particularly axially directly makes progress, like this; In speed-down action; Particularly in the brake, in direction backward and act under the effect of longitudinal force of point of attachment of wheel side, transverse link pivots making on the wheel internal beam direction of the point of attachment that can be connected to wheel side; Perhaps reduce the wheel that caused by speed-down action at least significantly outer, this will more describe in detail below.
Word " longitudinal force " in context of the present invention in fact along the power of the longitudinal axis of transverse link or directive effect in parallel.Longitudinal axis is established by the connection lead at the center of the pivot bearing that connects body side in fact, as in the above for illustrating term " pivot bearing " explains.Therefore, the pivot axis of the longitudinal axis of transverse link and body side is parallel to each other in fact.If longitudinal force acts on the direction of the pivot bearing of back body side at the pivot bearing of the past body side, after it points to.
Can design with known mode in essence according to the elastic bearing of transverse link of the present invention, for example, rubber-and-metal bearing, particularly rubber-and-metal bearing lining.If specific diameter is upwards more pliable and tougher, promptly more flexible, firmer than in the axial direction diametrically in other words in the axial direction for they, promptly rigidity is big and elasticity is little, and they can have the most various structure in order to reach this target.Therefore, because the radial deflection that elastic bearing stands when only acting on the elastic bearing diametrically such as the power of the identical size of fruit of the longitudinal travel of only making in the elastic bearing that the power on the elastic bearing causes in the axial direction is big.In this, we can say, confirm by the elastic behavior of elastic bearing equally according to tracking (tracking) property of transverse link of the present invention.
Because the preceding pivot bearing axis of the pivot bearing of each body side and/or back pivot bearing axis are with respect to the certain tilt of the pivot axis of above-mentioned pivot bearing establishment; According to the present invention; On the internal beam direction second rotated the rotation on the outer Zhang Fangxiang that can be added to; Like what when beginning, describe, above-mentioned rotation is caused by the moment of torsion that the rearward-directed force with respect to pivot bearing causes.Preceding pivot bearing axis and/or back pivot bearing axis tilt with respect to pivot axis as follows expediently or set; Promptly; The transverse link that causes by rearward-directed force also cause the introversive movement of front body side pivot bearing along the linear reverse of pivot bearing axis; Motion on promptly in fact from the point of attachment of wheel side to the direction of the pivot bearing of front body side; And/or the outside motion of pivot bearing of back body side, the motion on promptly in fact from the pivot bearing of back body side to the direction of the point of attachment of wheel side.With respect to transverse link, the inside and/or outside motion of this direction of the pivot bearing of body side causes the second above-mentioned favourable rotation on the internal beam direction.
According to leaning angle with respect to the leaning angle of the front pivot axis of selecting in advance of pivot axis and/or the back pivot line selected in advance; Therefore and to application force, allow the wheel of the point of attachment that can be connected in wheel side is carried out specific internal beam control according to transverse link of the present invention according to the back.Transverse link according to the present invention provides huge advantage: the additional components of correction wheel internal beam be can exempt, for example, intermediate rod or bundle angle correction coupler on the transverse link are connected in or are supported in, or other equipment that provide for this target.Transverse link according to the present invention has obtained the effect at some device correction bundle angles of independent use, particularly uses the pivot bearing of the body side that transverse link under any circumstance all is equipped with.Therefore, the structure according to transverse link of the present invention is able to simplify.In addition, because the omission of additional components, according to the structure space of transverse link needs of the present invention and therefore also have weight to reduce.Above-mentioned having superiority is equally applicable to use the wheel suspension according to transverse link of the present invention therein.
In preferred especially a structure according to transverse link of the present invention; Preceding pivot bearing axis tilts with respect to pivot axis with first jiao with regard to preceding vertical axis; Preceding vertical axis extends perpendicular to the main plane of being established by the point of attachment of pivot axis and wheel side of extending; And pass the center of the pivot bearing of front body side, and/or back pivot bearing axis just the back vertical axis tilt with respect to pivot axis with second jiao, back vertical axis passes the center of the pivot bearing of body side afterwards.Therefore, in this structure, preceding pivot bearing axis and/or back pivot axis with first and/or second jiao around before or after vertical axis rotation and therefore tilting with respect to pivot axis.Forward and backward vertical axis (=back S. A.) is established by the main center of extending the pivot bearing of plane and each body side of transverse link.
Before or after in the process of pivot bearing axis vertical axis rotation before or after separately, therefore the pivot bearing axis extends in the plane and tilts with respect to pivot axis in the horizontal main the extension in fact.In this case, refer in fact that laterally wherein connection lead and pivot axis are with right angle intersection by the point of attachment of wheel side and the direction of the establishment of the connection lead between the pivot axis.
Select in advance independently of each other and have no particular limits for first and second jiaos.According to the present invention, first jiao refers to current pivot bearing axis, as being seen in the planar view of transverse link, around preceding vertical axis conter clockwise, promptly when mathematical being rotated in the forward, by the preceding pivot bearing axis of transverse link and the folded angle of pivot axis of body side.According to the present invention, second jiao refer to when after pivot point out axis, as being seen in the planar view of transverse link, the vertical axis cw around the back is promptly when mathematical negative sense rotation, by the back pivot bearing axis of transverse link and the folded angle of pivot axis of body side.
Preceding pivot bearing axis provides special actv. bundle angle angle control advantage around the rotation of preceding vertical axis and/or the rotation of back pivot bearing axis vertical axis around the back.Because in the horizontal with respect to pivot axis before or after the pivot axis bevelled, the change that transverse link directly causes transverse link to rotate and therefore cause the bundle angle angle of point of attachment bonded assembly wheel that can be through body side around the rotation axis parallel with forward and backward vertical axis along each straight-line motion of pivot bearing axis.The nadir of this rotation axis of transverse link, promptly rotation axis passes the main point that extends the plane of transverse link, can rely on first and/or second jiao of change and therefore can adapt to design demand separately.
Especially, if first and/or second dihedral acutangulates in each case, promptly greater than 0 degree less than the angle of 90 degree, then the control of internal beam direction can be through obtaining according to transverse link according to the present invention.For the control on the outer Zhang Fangxiang, select the obtuse angle, promptly greater than 90 degree less than the angle of 180 degree, as first and/or second jiao.
For particularly advantageous internal beam control according to transverse link of the present invention; If first jiao from greater than 0 spend about 25 the degree scope in preferably favourable; Especially preferably spend about 20 degree from about 5, and most preferably about 10 degree, and/or second jiao preferred from spending in the scope of about 25 degree greater than 0; Especially preferably spend about 20 and spend from about 5, and most preferably about 10 degree.
In addition, for transverse link especially the letter but structure, first and second jiaos each all have preferred identical size.Especially, because the symmetrical feature of transverse link, this structure provides to simplify can use the design-calculated advantage according to the wheel suspension of transverse link of the present invention.
In addition; According to the present invention; Preceding pivot bearing axis tilts with respect to pivot axis with triangle with regard to preceding axis of pitch; Before axis of pitch extend in pivot axis in the main central vertical of extending in the plane and passing the pivot bearing of front body side, and/or back pivot bearing axis just the back axis of pitch tilt the center of the pivot bearing of body side after back axis of pitch passes with respect to pivot axis with the 4th jiao.Therefore, in this structure, preceding pivot bearing axis and/or back pivot bearing axis with the 3rd with/the four jiao around preceding with/back axis of pitch rotation and therefore tilt with respect to pivot axis.Before with back axis of pitch (=rotation axis) transverse link main extend extend in the plane and and the pivot bearing that respectively extend through front body side vertical with the pivot axis of body side with after the center of body side pivot bearing.
In the process of preceding and/or the axis of pitch rotation before or after separately of pivot bearing axis, therefore the pivot bearing axis extends in main extension plane in fact and is extending on the vertical direction in plane to tilt with respect to pivot axis with main.
Select in advance independently of each other and have no particular limits for third and fourth jiao.According to the present invention; Triangle refers to work as front pivot axis, as being seen the lateral plan of body side pivot bearing forward from the point of attachment of wheel side, around preceding axis of pitch conter clockwise; Promptly when mathematical being rotated in the forward, by the preceding pivot bearing axis of transverse link and the folded angle of pivot axis of body side.According to the present invention; The 4th jiao refer to when after pivot axis, as being seen the lateral plan of the pivot bearing of body side forward from the point of attachment of wheel side, the axis of pitch cw around the back; Promptly when mathematical negative sense rotates, by the back pivot bearing axis of transverse link and the folded angle of pivot axis of body side.
When the motion of design consideration transverse link of the present invention, the extra degree of freedom that preceding pivot bearing axis provides around the rotation of the rotation of preceding axis of pitch and/or back pivot bearing axis axis of pitch around the back.
Triangle is preferred from spending in the scope of about 25 degree greater than 0, especially preferably spends about 20 degree from about 5, and most preferably about 6 degree.The 4th jiao preferred from spending in the scope of about 25 degree greater than 0, especially preferably spends about 20 degree from about 5, and most preferably about 6 degree.
In addition, for the especially simply structure of transverse link, third and fourth jiao each all have preferred identical size.Especially, because the symmetrical feature of transverse link, this structure provides to simplify and can use the design-calculated advantage according to the wheel suspension of transverse link of the present invention.
In a particularly advantageous mode, elastic bearing axially on rigidity the rigidity that makes progress of specific diameter is low in fact.Especially, axially compared preferably approximately 1: 10 with radial rigidity.When power in fact vertically, when promptly being applied to it on axially, this allows through utilizing the longitudinal travel in the elastic bearing to carry out specific internal beam control.
In addition, the elastic bearing of the pivot bearing of forward and backward body side can according to its axially and/or the rigidity that makes progress of footpath carry out different designs.Therefore, the tracking property according to transverse link of the present invention can change in very wide scope through the elastic behavior of selecting elastic bearing in advance equally.
In a particularly advantageous mode, according to transverse link of the present invention, because its simple structure can use in the wheel suspension of the non-wheel flutter that is used for power actuated vehicle, particularly rear wheel suspension.For this target, the pivot bearing of front vehicle wheel side and the pivot bearing of rear wheel side are provided at the point of attachment of wheel side.The pivot bearing of the pivot bearing of front vehicle wheel side and rear wheel side is established the pivot axis of wheel side.Wheel stand can be connected to the pivot bearing of wheel side pivotally.
The use of transverse link according to the present invention in the rear wheel suspension of power actuated vehicle provides huge advantage: the characteristic of proofreading and correct the transverse link of internal beam has been offset the oversteer tendency of rear driving axle under the deceleration situation.

The specific embodiment
Identical part provides same reference numerals all the time in different accompanying drawings, therefore common above-mentioned part is also only described once.
Preferred illustrative embodiment according to transverse link 1 of the present invention representes with different views in Fig. 1-3.In body side, transverse link 1 has preceding pivot bearing 2 and back pivot bearing 3.By way of example, elastic element 4 is Elastic Cylindrical lining 4 specifically, and for example the rubber-metal lining is contained in the pivot bearing 2,3.Through resilient bushing 4 or through pivot bearing 2,3, transverse link 1 can be connected to vehicle body (not shown) or subframe pivotally.
At transverse link 1 middle part, it has the storing apparatus that is respectively applied for coil spring 8 and damping element 9.Coil spring 8 and damping element 9 can be connected to vehicle body (not shown) or subframe away from the far-end of transverse link 1.
In wheel side, the pivot bearing 10 of front vehicle wheel side and the pivot bearing 11 of rear wheel side are provided on transverse link 1.Shown in exemplary embodiment in, the pivot bearing of wheel side 10,11 forms the wheel side point of attachment 7 of transverse links 1.As the same in pivot bearing 2 and 3, typically, similar resilient bushing is contained in pivot bearing 10 and 11.The transverse link of this pattern is also referred to as trapezoidal connecting rod (trapezoidal link).
Mutual in fact in-line of the pivot bearing axis of the pivot bearing 10,11 of wheel side and the difference preceding connection supporting leg 13 and the back of supporting wheel support 12 pivotally connect supporting leg 14.Wheel stand 12 also is supported on the last shaft-like connecting rod 16 that takes the shape of the letter U in fact to connect supporting leg 15 on it similarly pivotally.Shaft-like connecting rod 16 can be connected to automobile body (not shown) or subframe pivotally with its far-end away from wheel stand 12.The wheel 17 of power actuated vehicle (being shown in accompanying drawing 4A and 4B) can be rotatably connected to wheel stand 12.Can certainly on wheel stand 12, arrange above-mentioned coil spring 8 and damping element 9.
The body side pivot axis 23 of transverse link 1 can see in Fig. 2 that above-mentioned pivot axis 23 passes the center of the pivot bearing 2,3 of forward and backward body side.Shown in exemplary embodiment in, 23 one-tenth first jiao 30 of preceding pivot bearing axis 5 and pivot axis.Before pivot bearing axis 5 extend main the extension in the plane 22 in fact, this can see in Fig. 3, and around preceding vertical axis 25 left-hand revolutions, this equally also can see in Fig. 3, and therefore with respect to pivot axis 23 inclinations.In a similar manner, back pivot bearing axis 6 around back vertical axis 26 clickwises and therefore with 23 one-tenth second jiao 31 of pivot axis.Back pivot bearing axis 6 also extends in the main extension plane 22 of transverse link 1 and only tilts with respect to pivot axis 23 with respect to back vertical axis 26.
In the exemplary embodiment of transverse link shown in Figure 2, first jiao 30 has identical in fact size, preferred identical size with second jiao 31.The extended line of their axis of pivot bearing separately 5,6 intersects at a point, when in planar view, observing, and this lateral deviation wheel axis 18.
Because pivot bearing axis 5,6 extends main the extension in the plane 22 in fact, like what describe in the above, for shown in the exemplary embodiment of transverse link 1, it is big or small next to be that third and fourth jiao of (not shown) preferably has 0 degree.But pivot bearing axis 5,6 also can rotate to main the extension outside the plane around axis of pitch 27 and 28 respectively, and axis of pitch 27 and 28 is illustrated among Fig. 2, and also can on this direction, tilt with respect to pivot axis 23.The present invention can be advantageously with pivot bearing with its pivot bearing axis 5,6 or resilient bushing 4 with respect to pivot bearing axis 23 with first and second jiao 30,31 and/or with third and fourth jiao of setting.
As can also see that when on longitudinal extension direction 20, observing, front truck side pivot bearing 2 is arranged far apart from wheel axis 18 than front vehicle wheel side pivot bearing 10 from Fig. 2.In addition, when on longitudinal extension direction 20, observing, aftercarriage side pivot bearing 3 is arranged far apart from wheel axis 18 than rear wheel side pivot bearing 11.
In addition, car body side pivot axis 23 extends in parallel with wheel side pivot axis 24 in fact.
Fig. 4 A and 4B schematically represent with mode of comparing; Act on the wheel 17 that does not have according on the transverse link 34 of characteristic of the present invention; And act on longitudinal force 33 according to the wheel 17 on the transverse link 1 of the present invention, be the effect of brake weight backward specifically.The difference of representing among transverse link 34 shown in the accompanying drawing 4A and Fig. 4 B according to transverse link 1 of the present invention is the direction of pivot bearing 36 of pivot bearing 35 and its aftercarriage side on its front truck side.In transverse link 34, preceding pivot bearing axis 37 and back pivot bearing axis 38 in-lines are different from transverse link according to the present invention and have pivot bearing 23.All further features of transverse link 34 are identical with the characteristic according to the exemplary embodiment of transverse link 1 of the present invention shown in Fig. 1-3.
The pivot bearing 2,3 of transverse link 1 and pivot bearing 10 and 11 and the pivot bearing 35,36 of transverse link 34 all have resilient bushing 4.Resilient bushing 4 has the elastic behavior with respect to its axial stiffness and radial rigidity that the front has been described equally, and promptly they are designed to the rigidity that makes progress of footpath big than on axially in fact.
If brake weight 33 acts on wheel 17 at this moment on the direction of arrow; Shown in Fig. 4 A signal; The pivot bearing 35 on front truck side is outwards drawn diametrically and the pivot bearing 36 of aftercarriage side is extruded inward diametrically, shown in the corresponding arrow on pivot bearing 35,36 separately.In addition, car body side pivot bearing 35,36 moves along pivot axis 23 backward, same as corresponding arrow signal.The radial load of pivot bearing 35,36 and therefore the radial load of resilient bushing 4 cause rotatablely moving of transverse link 34; Therefore the direction that this rotatablely moves in figure plane is a conter clockwise, and causes the wheel 17 bundle angle angular adjustment 39 on the Zhang Fangxiang outside.
Be shown schematically among Fig. 4 B with identical speed-down action shown in Fig. 4 A.Because the following fact: in transverse link 1 according to the present invention; The pivot bearing 2 on front truck side and the pivot bearing of aftercarriage side 3 tilt with respect to pivot axis 23 according to the present invention; As through being explained with reference to figure 1-3; So when power 33 acted on wheel 17, preceding pivot bearing 2 in fact inwardly and backward moved along its pivot axis 5, shown in the corresponding arrow on the preceding pivot bearing 2.On the contrary, back pivot bearing 3 outwards with backward moves, equally shown in corresponding arrow.The axial motion of this pivot bearing axis 5,6 along pivot bearing 2,3 causes rotatablely moving of transverse link 1, and the above-mentioned direction that rotatablely moves is a cw in figure plane, promptly causes making wheel 17 on the internal beam direction, to restraint rotatablely moving of angle angular adjustment.On rotatablely moving is rotatablely moving from the outer Zhang Fangxiang that is known with respect to the described situation of Fig. 4 A being superimposed upon this on the internal beam direction, because the pivot bearing 2 of front body side is extruded inward by the pivot bearing 3 of outside extruding and aftercarriage side equally diametrically equally diametrically.Therefore, in the situation shown in Fig. 4 B, the whole bundle angle angular adjustment 40 that obtains the correction of wheel 17, the uncorrected bundle angle angular adjustment 39 than the transverse link shown in Fig. 4 A 34 is little in fact in above-mentioned bundle angle adjustment 40.The appropriate designs of the elastic characteristic through resilient bushing 4 and first and second jiao 30,31 suitablely select in advance; In the deceleration situation shown in Fig. 4 B; Can obtain the rotatablely moving of the internal beam direction that rotatablely move of transverse link 1, so cause the bundle angle angular adjustment of wheel 17 on the internal beam direction greater than the outer Zhang Fangxiang of compensation.
The transverse link 1 of utilization shown in Fig. 1-4, through selecting first and second jiao 30,31 and the elastic behavior of resilient bushing 4 in advance, the tracking of wheel 17 (tracking) property can change in very wide scope.
In a preferred embodiment, transverse link 1 is designed to the lower trapezoid connecting rod of the wheel suspension of the non-wheel flutter of power actuated vehicle, particularly rear wheel suspension.
Can be expressed as the CAE simulation through the example among Fig. 5 through the effect around the rotation of vertical axis that the present invention obtains during the brake, promptly brake weight turns to the function as the rotation of interior pivot bearing 2 and 3.The X axle representes that lining or pivot bearing are around the rotation of vertical axis (angle initialization for [°]).Lining or pivot bearing are all with identical size variation.The tracking property of Y axle during with [°/kN] expression brake (brake weight turns to).Can find out that rotation has favourable effect, and has about 11 ° best angle (arrow 41), arrow 42 expressions " slight oversteer ".Exemplary best size is applicable to distance and the distance between pivot axis 23 and 24 between fixing pivot bearing 2 and 3.The change of these geometric relationships can cause small different best angles.The effect that the present invention obtains still keeps.
If in order to obtain the pivot bearing 10 and 11 of forward and backward wheel side suitably to be set respectively through the effect of the present invention's acquisition, this also within the scope of the invention.Aspect this, back pivot bearing 2 and 3 can suitably be set adapting with the pivot bearing 10 and 11 of wheel side respectively respectively, or each pivot bearing 2 and 3 or 10 and 11 can be provided with voluntarily.
